LIQUID-RESERVE DEVICE.

Application filed June 19, 1922. Serial No. 569,459.

To all whom it may concern Be it known that I, RoLLf1 E. MUDD, a citizen of the United States, and a resident of Chica-go, in the county of Cook and State of Illinois, have invented a new and useful lmprovement in Liquid-Reserve Devices, of which the following is a full, clear, and-exact description.

My invention relatesto improvements in liquid reserve devices, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide a liquid reserve device, which is adapted to be used in connection with the outlet of a gasoline tank for the purpose of reserving a part of the liquid therein, to be used in an emergency. ,i

A further object of my invention is t provide a device of the t-ype described, which is adapted to drain gasoline from the bottom of the tank, thereby preventing any water which might be in the gasoline from accumulating in the tank.

A further object of my invention is to provide a device which is particularly adapted for use with gravity fuel feed systems without any necessity of change in any of the parts.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which- *igure l is a central section through the device, showing its conection with atank and sediment bulb, and

Figure 2 is a section along the line 2-2 of Figure l..

In carrying out my invention, l make use of a casing consisting preferably of a lower polygonal. portion 1 and an integral cylindrical portion 2. The latter is closed at its upper end, as shown at 3, with the exception of a small opening 4. Between the upper portion 2 and the lower portion 1 is a threaded portlon 5, which is arranged to enter thethreaded opening in the bottom of a gasoline tank 6. Y

The lower end of the casing is provided with a threaded opening 7. Extending longitudinally of the device are two passageways 8 and 9 respectively, these passageways being separated by a partition 10 which terminates Vshort of the top of the casing, and which extends to thethreaded opening 7. The wall of the cylindrical portion 2 has an opening 11 leading into' the passage-way 8 just above the bottom ofthe tank. A valve 13 controls the passage-way 8.

From the foregoing description ofthe various parts of thel device, the operation thereof may be'readily understood. In attaching the deviceto gravity fuel feed systems, such as that used in the Ford car, the ordinary sediment bulb at the bottom of the tank is unscrewed and removed, and the cylindrical portion 2 of the casing is thrust through the opening, the casing being screwed into position, so that the upper end will extend some distance above the bottom of the tank. The sediment bulb 14 is then screwed into the threaded opening 7, the pipe 15 at the bottom of the sediment bulb communicating with the carburetor (not shown) 1 Normally, the valve 13 is closed, and as the fuel is used-from the carburetor, the fuel in the tank will pass through the opening 11, thence iiow over the partition 10 and downwardly through the passage-way 9, and through the sediment bulb, through the pipe 15, and thence to the carburetor. Any water contained in the gasoline will be carried along with it, and will be caught in the sediment bulb in the usual manner, thus keeping the tank free from water. 7hen the level of the fuel in the tank reaches the line x-, then the flow of fuel will cease, after that in the passage-way' 9 has drained out. The driver of the vehicle may then have access to the portion which is left in the tankby opening the valve 13.

t is obvious that the reserve supply will depend upon the height of the partition 10 above the bottom of the tank, and I contemplate making these reserve devices in greater or less lengths, so as to reserve a greater or less supply of fuel, depending upon conditions to be met. x

I am aware that it is not new to have emergency compartments in Vconnection with fuel tanks. Such is not my invention broadly. It will be observed, however, that in using my device, the'ordinary tank is used without any change. My device merely serves as as a connection between the ordinary tank and the ordinary sediment' bulb, such as that used on the Ford cars. The provision of the small opening 4 provides an inlet for air when the liquid has reached the top ot the partition l0, so that the drain ing or' the passage-way 9 does not Siphon ott the tank. The opening at, however, is so small that the greater portion of the fuel entering the device normally passes through the opening 11 and up and around the partition l0, carrying water with it, as stated, which may be contained in the fuel.

l claim: Y

l. The combination with a gravity fuel V{"eed tank of a reserve Supply device oom- Y rising a easing arranged to extend through the bottom of the tank and into the interior ot the latter, the top ofthe easing being normally below the level of the liquid fuel, Said *asing havinp a Small air openingat its top, and being provided with two passage-ways communicating with each other at the upper portion o' the caring, one ot said passage ways being in Communication with the interior of the tank near the bottom thereof, and the other extending` to the bottom ot' the casing. Y

2. A casing Comprising a lower body portion, an upper reduced portion, and an intermediate threaded portion, Said upper portion having a Small air opening at its top, a partition terminating short of the upper end to provide a pair ot passage-ways communieating' at their upper end, said easingv having an opening` in its wall for affordingl com munieation trom the interior ot' the tank to one of said passage-ways near the bottom ot the tank, and a valve disposed in the last named passage-way for controlling the How of liquid.`
